Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

This data storage system has transparent or reflective storage medium 1 including magnetic film 2 on which data is stored by magnetic head 3. The latter includes a plurality of separately energizable sections 4 which are used to store a single hologram representative of the data. For readout, polarized light beam 5 is generated by laser 6, directed through polarizer 7, and reflected toward medium 1 by mirror 8. Using the Faraday effect, beam 5 passes through medium 1 to analyzer 9 and is detected at photodiodes 10 to read the data. When a reflective storage medium is used, readout can also be accomplished by the Kerr magneto-optic effect in a similar manner.

Magnetic Recording and Optical Readout System

This data storage system has transparent or reflective storage medium 1
including magnetic film 2 on which data is stored by magnetic head 3. The latter
includes a plurality of separately energizable sections 4 which are used to store a
single hologram representative of the data. For readout, polarized light beam 5 is
generated by laser 6, directed through polarizer 7, and reflected toward medium
1 by mirror 8. Using the Faraday effect, beam 5 passes through medium 1 to
analyzer 9 and is detected at photodiodes 10 to read the data. When a reflective
storage medium is used, readout can also be accomplished by the Kerr
magneto-optic effect in a similar manner.
